A circular swimming pool is 40 inches in diameter. What is the circumference of the swimming pool?

125.6 inches

Step-by-step explanation:

Diameter (d) = 40 inches

circumference (c)

= π * d

= 3.14 * 40

= 125.6 inches

Hope it will help :)

125.6

Step-by-step explanation:

diameter= 40

40 x π = 125.6

40 x 3.14 = 125.6

17 + .11x = 22 + .07x

      .04x = 5

          x = 5/.04   = 125 minutes, is the number of minutes the two plans cost the same

  17 + .11*125 = $30.75 is the cost when the two plans cost the same
